Hello dear artists, IES lights doubt

[AndresAhumada]

Anyone know if it still remains the fastest calculation based on IES files right through the VRayIES lights? compared with classical photometric lights.

Greetings to all.

The calculations are faster with V-Ray Ies lights.
I have a small example test render here.

The scene has 40 Standard Ies lights and 40 V-Ray Ies lights.
